i've tried using date_diff and date_create to get a difference from two date that's already converted to string.
here's the code:
$date_1 = date_create();
$date_now = date_format($date_1, 'Y-m-d');
//echo $date_now . "\n";
$date=date_create($date_now);
date_add($date,date_interval_create_from_date_string("3 days"));
$date_return = date_format($date,"Y-m-d");
$diff = date_diff(date_create($date_now), date_create($date_return));
echo $diff;
and i am getting this error:
Object of class DateInterval could not be converted to string
You need to call DateInterval::format()
to display that difference as a string.
echo $diff->format('%d days');
See the manual for all of the available formatting options.
